Detailed Description

Brief information on parallel subdomain replication.

Replication consists of taking a set of parallelMng() and duplicating this set several times, each set performing in principle the same treatment unless explicit code dictates otherwise. For example, it is possible to have a calculation that is performed generally on 8 subdomains, and replicate this set 4 times. This then uses the equivalent of 32 processes.

This class contains the information on replication and is accessible via IParallelMng::replication().

Member Function Documentation

hasReplication()

virtual bool Arcane::ParallelReplication::hasReplication ( ) const

inlinevirtual

Indicates if replication is active.

Implements Arcane::IParallelReplication.

Definition at line 64 of file ParallelReplication.h.

isMasterRank()

virtual bool Arcane::ParallelReplication::isMasterRank ( ) const

inlinevirtual

Indicates if this replication rank is the master.

This is useful for example for outputs, so that only one replica outputs the information.

Implements Arcane::IParallelReplication.

Definition at line 67 of file ParallelReplication.h.

masterReplicationRank()

virtual Int32 Arcane::ParallelReplication::masterReplicationRank ( ) const

inlinevirtual

Rank in the master replication.

Implements Arcane::IParallelReplication.

Definition at line 68 of file ParallelReplication.h.

nbReplication()

virtual Int32 Arcane::ParallelReplication::nbReplication ( ) const

inlinevirtual

Number of replications.

Implements Arcane::IParallelReplication.

Definition at line 65 of file ParallelReplication.h.

replicaParallelMng()

virtual IParallelMng * Arcane::ParallelReplication::replicaParallelMng ( ) const

inlinevirtual

Communicator associated with all replicas representing the same subdomain.

Is 0 if there is no replication (hasReplication() is false).

Implements Arcane::IParallelReplication.

Definition at line 69 of file ParallelReplication.h.

replicationRank()

virtual Int32 Arcane::ParallelReplication::replicationRank ( ) const

inlinevirtual

Rank in the replication (from 0 to nbReplication()-1).

Implements Arcane::IParallelReplication.

Definition at line 66 of file ParallelReplication.h.
